What is Interactive Voice Response?
Let me google that for you… Interactive voice response. The real difference between Interactive Voice Response and Speech Recognition (Automatic Speech Recognition) is that IVR is primarily based on selective, pre-programmed pattern recognition, actually something similar to AIML chatbots; whereas, ASR theoretically works on a higher level, recognizing more sounds and more phrases, if not all. Other than in a practical sense (IVR does less, ASR does more), I’m not convinced the distinction is really valid; I strongly suspect a clever person could program IVR to work better than ASR programmed by a dull person.
